Application 1 1;; c8, 1950,SerialNo.17 6,48i)

This invention comprises novel and useful improvements in door knobs,and more particularly pertains to a door knob having a crown bottle capremover thereon.

An important object of this invention is to provide a door knob whichhas a crown bottle cap remover mounted thereon, and which combinationdoor knob and bottle cap remover is adapted to be mounted on a dooractuating rod and which will consequently be disposed at a convenientheight for use.

Another object of this invention is to provide a combination door knoband bottle cap remover which is of simple construction, and which may bereadily manufactured, and which combination knob will have anefficacious appearance.

Various important features of this invention reside in the provision ofa door knob which includes an enlarged portion having a sleeve portionformed integrally therewith, and which sleeve portion is adapted to bemounted upon a door actuating rod, and which enlarged portion has arecess in the face thereof which is disposed perpendicular to the sleeveportion, with a crown bottle cap remover disposed in the recess.

These, together with various ancillary objects and features, areattained by this device, a preferred embodiment of which has beenillustrated by way of example only in the accompanying drawings,wherein:

Figure 1 is a fragmentary perspective elevational view of thecombination door knob shown mounted upon a door; and

Figure 2 is a fragmentary longitudinal sectional view of the combinationdoor knob and bottle cap remover, shown mounted upon a door.

Figure 3 is a top plan view of the device.

I-Ieretofore bottle cap removers were customarily mounted on walls andon the molding and casings of doors and windows, and when so mountedthey generally detracted from the appearance of the surface to whichthey were attached. It is a desideratum of this invention to provide abottle cap remover which may be mounted upon the door lockactuating rodin a convenient position for use, and which, when so mounted, will havean efiicacious appearance.

Referring now more specifically to the accompanying drawings whereinlike numerals designate similar parts throughout the various views, itwill be seen that the combination door knob and bottle opener, indicatedgenerally by the numeral l0, includes an enlarged portion l2 and areduced portion 14, preferably formed integrally with the enlargedportion.

'ii' ti a i g (01. 81-31) The reduced portionsisprovided withfa1ong'itudinall'y' extending,' and preferably internally threaded borel6, and which bore is adapted to receive a correspondingly externallythreaded door lock actuating rod I8. Alternately, the bore l6 may beinternally splined, so as to receive the correspondingly splinedactuating rod, in the event that externally splined rather than threadedrods are utilized. As is well known, rotation of the rod I8 upon itslongitudinal axis actuates the door lock mechanism, indicated generallyby the numeral 20, disposed in a door 22, the rod l8 extending throughan aperture 24 in the door. As is also customary, a suitable face plate26 may be attached to the door 22.

The enlarged portion l2 of the combination door knob 10 may be of anyconfiguration, but it is preferred that one face such as 28 liesubstantially perpendicular to the axis of rotation of the knob, andwhich face is provided with a recess 30 to receive the crown bottle capremover 32. In this manner, it will be appreciated that the bottle capremover will not detract from the appearance of the door knob, and sincedoor knobs are customarily located at convenient heights, the bottleopener will also be disposed in a convenient position for use.

The bottle cap remover 32 includes a perimetric wall 34 which is adaptedto be snugly received within the recess 30, the upper portion 36 of thewall 34 having a downwardly extending flange 38 formed integrallytherewith and adjacent the outer edge thereof for engagement with thelower edge of the rim of a crown bottle cap. An car 40 projects upwardlyand inwardly from the lower portion 42 of the perimetric wall 34, whichlug is adapted to engage the top of a crown bottle cap and provide afulcrum about which the bottle is pivoted to remove the cap. It will beappreciated that since the crown bottle cap remover 32 is disposedperpendicular to the axis of rotation of the knob H], the force exertedwhen removing a cap from a bottle, by engaging the lower edge of theskirt portion of the cap underneath the flange 38 with the top wall ofthe cap pivoting about the ear 40, will be substantially parallel to theaxis of rotation, and consequently the tendency to bend th actuating rodis materially reduced.

The bottle cap remover 32 may either be molded integrally with theenlarged portion l2 of the door knob In or, alternatively, may befastened thereto by means of pins, such as M.

The sleeve portion M of the knob I0 may additionally be provided with atransverse bore 46, which will protect the bore l 6, and which trans- 3verse bore may also be internally threaded to receive a set screw 48which is adapted to be tightened against the actuating rod [8 to preventrelative turning of the knob and actuating rod.

From the foregoing, it is thought that the operation and construction ofthis device will be readily understood, and further discussion istherefore believed to be unnecessary. However, since numerousmodifications will readily occur to those skilled in the art after aconsideration of the foregoing specification and accompanying drawing,it is not intended to limit the invention to that shown and described,but all suitable modifications may be resorted to falling within thescope of the appended claim.

Having described the invention, what is claimed 4 outer end having arecess therein, and a bottle cap removing unit secured in the recess,the upper marginal portion of said outer end of the head and theadjacent portion of said unit being substantially synclinal and flushfor centering the cap to be removed in said unit.
